Who was doing the Jeep transmissions with the Chevy bolt pattern and 904 gear sets?

Well from the wiki, the 80 - 87 Jeeps with the 2.5L. I assume the 232 & 256 six cylinders came with a different bellhousing pattern.

I think those were Pontiac Iron Duke engines put in Mail trucks .

I think that combo also came in an AMC Spirit.

The postal van transmissions were the only one with the chevy V8 bellhousing, nothing AMC. Not sure if they were 904's or 998's, never seen one. Would be a great find if they were 998's.

They were earlier Postal Jeeps that had the Chevy II 153 4 cylinder.
Fully loaded, the PG wouldn't cut it, so they needed a 3 speed... I thought A-1 did them at one time.

Was 1972 the last year for a Powerglide?

The 904 trans was in Jeeps with the 4 cyl iron duke in the early 80's. They were in 85 Cherokee with the 173 chevy V6 - I bought one new! in 85. The low gearset (2.74) was in some Matador and Spirit cars with the 4 cyl AMC motor in 80's - I bought several transmissions for the gearset at $100. The 6 and 8 cyl AMC's all have the same bolt pattern with 2 3/8 bolts up top and 2 7/16 bolts on the bottom going thru the dowels.

Interesting , but those are not the ones with the standard Chevy bolt pattern.
